Suppose I have a variable, FRED, whose value is a place
descriptor for SETF, like (get 'joe 'eye-color), and I
would like to SETF into the place described by FRED's
value. Is there any nice way of doing this? I couldn't
figure one out. Any help would be appreciated. 
   (I do realize that the method can't be determined 
until run-time because it might differ for
different values of FRED. I'm willing to pay any cost
associated with that. I just don't know any nice means of
telling lisp to do it.)
    Thanks
